| 英文摘要 | A study of b-s(0) -> eta(c)phi and b-s(0) -> eta(c)pi(+)pi(-) decays is performed using pp collision data corresponding to an integrated luminosity of 3.0 fb(-1), collected with the lhcb detector in run 1 of the lhc. the observation of the decay b-s(0) -> eta(c)phi is reported, where the eta(c) meson is reconstructed in the p (p) over bar, k+k-pi(+)pi(-), pi(+)pi(-)pi(+)pi-and k+k-k+k-decay modes and the phi(1020) in the k+k-decay mode. the decay b-s(0) -> j/psi phi is used as a normalisation channel. evidence is also reported for the decay b-s(0) -> eta(c)pi(+)pi(-), where the eta(c) meson is reconstructed in the p (p) over bar decay mode, using the decay b-s(0) -> j/psi phi pi(+)pi-as a normalisation channel. the measured branching fractions are b(b-s(0) -> eta(c)phi) = (5 : 01 +/- 0 : 53 +/- 0 : 27 +/- 0 : 63) x 10(-4), b(b-s(0) -> eta(c)pi(+)pi(-)) = (1 : 76 +/- 0 : 59 +/- 0 : 12 +/- 0 : 29) x 10(-4), where in each case the fi rst uncertainty is statistical, the second systematic and the third uncertainty is due to the limited knowledge of the external branching fractions. |
